Conclusions
-
1.
ML is the result of crack formation in the hybrid composite material.
-
2.
The loss of continuity in uniaxial loading can be recorded both by the ML method and (in individual cases) by strain gauging.
-
3.
For the hybrid composite in combined loading in the plane stress state, ML indicates (in contrast to strain gauging) the instant of the start of cracking.
